Study Notes
Light and Optics Concepts
- Polarization: Alignment of light waves in a single vibrational direction.
- Concave Mirror: A mirror that converges parallel light rays at a focal point.
- Photoelectric Effect: A phenomenon that can only be explained by light's particle model, where light causes electron emission from metal.
- Taylor's Experiment: Demonstrated that individual photons exhibit wave-like characteristics.
- Reflection: The primary use of mirrors, involving the bouncing back of light.
- Virtual Images: Images produced by convex mirrors, which cannot be projected on a surface.
- Mirage: An optical illusion where the sky appears reflected on a hot surface, caused by temperature gradients in air.
- Diffraction: A pattern formed by light passing through a narrow opening.
- Dispersion: The process of separating light into its component colors.
Refraction and Index of Refraction
- Index of Refraction Calculation: If light slows from 3.00 x 10^8 m/s in air to 2.00 x 10^8 m/s in another medium, the index of refraction can be calculated as n = 1.50.
- Sine Values of Angles: Given that the sine of the incident angle is 0.217 and the sine of the refracted angle is 0.173, the index of refraction is found to be n = 1.25.
Image Formation with Lenses and Mirrors
-
Image Characteristics: For an object located beyond twice the focal length of a converging lens, the image produced will be:
- Inverted
- Real
- Diminished
-
Converging Mirror: An object 4 cm tall placed 10 cm from a converging mirror with a focal length of 5 cm produces:
- A real image
- An inverted image
- An image of the same size as the object
Total Internal Reflection
- Conditions for Total Internal Reflection: Occurs when light travels from a low-velocity medium to a high-velocity medium at an incident angle greater than the critical angle.
